The Darker Side Of God
If you ask Christians to describe their quasi-chosen god of worship,
you’ll often hear such descriptors as “wonderful” and “loving.” This
choice of selective designation seems commonplace within the Christian
community. In fact, most churches ignore the Old Testament all together so
that the members feel comfortable propagating this view. Fueled by such
blatant omission, this lengthy chapter will fill the void by offering a look
at the volume of horrendous acts perfo... 阅读全帖

Forgive my digression, but I have to mention how babies start their

In the womb of the monther, baby gets all s/he needs through the
placenta. When s/he leaves mother's body, the higher concentration
of carbon dioxide(CO2) stimulates the nervous system. A simple

Emissions of greenhouse gases from human activities are changing the

用氮气取代氧气造成窒息,应该人没感觉。
An asphyxiant gas is a nontoxic or minimally toxic gas which reduces or
displaces the normal oxygen concentration in breathing air. Breathing of
oxygen-depleted air can lead to death by asphyxiation (suffocation). Because
asphyxiant gases are relatively inert and odorless, their presence in high
concentration may not be noticed, except in the case of carbon dioxide (

认可。至此,美国科学院院士总人数达到2291人,外籍院士人数达到465人。
杨培东是中国科学技术大学校友中的第三位美国科学院院士。——2012年5月1日,骆利
群(81少)、庄小威(87少)等两位中国科大少年班校友荣膺院士。因此,杨培东的当
选也开创了中国科大校史上的两个先例:他是第一位当选该院院士的非少年班校友,也
是第一位从事非生命科学研究且当选该院院士的科大人。传统上,很多人认为中国科大

Question: What Is the Difference Between Baking Soda & Baking Powder?
Answer: Both baking soda and baking powder are leavening agents, which means
they are added to baked goods before cooking to produce carbon dioxide and
cause them to 'rise'. Baking powder contains baking soda, but the two
substances are used under different conditions.
Baking Soda
Baking soda is pure sodium bicarbonate. When baking soda is combined with
moisture and an acidic ingredient (e.g., yogurt, chocolate, buttermilk,

China Grapples With A Burning Question
Josh Fenn*
In the coming weeks, on the plains of Inner Mongolia, China will launch its
first large-scale effort to capture and store carbon emissions from a power
plant. A new coal-to-liquid plant in Erdos will burn coal to make, at the
outset, a little over 1 million metric tons per year of diesel and other
petrochemicals, generating as a byproduct nearly 4 million tons of carbon
dioxide (CO2) a year. In an effort to make carbon capture pay, much of the

你们都没看过 musk 关于火星计划的那次发布会?
他打算多次分批运送机器和材料到火星,搭建基地。基地搭好了,在火星上造燃料。
"SpaceX also plans to build a solar-powered factory on Mars that will use
the carbon dioxide and water ice in the planet's air and soil, respectively,
to generate methane and oxygen — the propellant used by the Raptor engine."

Mars Through a Small Telescope
Credit & Copyright: Francisco A. Rodriguez Ramirez (AstroEduca)
Explanation: How does Mars appear through a small telescope? Viewed with the unaided eye
or through a small telescope, possibly the most striking part of Mars' appearance is its red
color. The color derives from rust, iron oxide, which composes perhaps 10% of the Martian
soil. The oxygen that rusts the surface iron on Mars originates predominantly from carbon
dioxide gas, which composes 95% of

发信站: BBS 未名空间站 (Tue Feb 24 08:51:52 2009)
Nasa's first mission to measure carbon dioxide (CO2) from space has failed
following a rocket malfunction.
Officials said the fairing - the part of the rocket which covers the
satellite on top of the launcher - had failed to separate properly.
Officials said the satellite had now crashed in Antarctica.
The Orbiting Carbon Observatory (OCO) was intended to help pinpoint the key

吃素一天的惊人效应
有时候,世界上最大问题的解决方桉就在我们眼前。下面的统计数据至少可说,真令人
大开眼界。我曾广泛撰写肉食对我们健康,我们「正确生活」的感觉,及对环境的影响
。其中每天的习惯之一有着非常广泛和深远的影响,我认为值得从各种不同的观点一再
的检视。有时候,世界上最大问题的解决方桉就在我们的面前。
下面的统计数据至少可说是令人大开眼界。如果每个人都只吃素一天,美国将节省:
●一千亿加仑的水,足以供应新英格兰近四个月所有房屋之需;
●十五亿英磅喂给牲畜的作物,足以养活新墨西哥州民一年多;
●七千万加仑天然气,足以提供加拿大和墨西哥所有汽车的燃料,而有馀甚多;
●三百万英亩的土地,两倍于德拉瓦州面积大小;
●三十三吨的抗生素。
